Tom and Emily kick off a brand-new three-part miniseries on how people understand (and misunderstand) carbon removal - and what that means for the future of the sector. From the words we choose to the baggage they carry, from early “sci-fi” scepticism to today’s governance debates, this episode unpacks why public perceptions aren’t a side issue: they’re central to whether CDR can scale at all.

In this episode:

🧠 Low Awareness, High Stakes: We look at why knowledge of CDR remains tiny - and yet how support rises sharply once people actually learn what it is.

📜 Early CDR Was… Science Fiction: Back in the noughties, carbon removal felt like aviation before the Wright brothers. But have we caught up?

🗣️ The Language Trap: “Ocean acidification”, “nature-based”, “engineered”: the words we choose shape the reactions we get. We hear why analogies can mislead, why metaphors can create false binaries, and why the “natural = good” instinct is more complicated than it looks.

🌏 When Context Changes Everything: From smallholders in Malaysia to farmers in Cornwall, public perceptions aren’t static - they’re contextual.

🏛️ Governance Isn’t Background Noise: We learn that CDR isn’t just hardware. Change the governance model, and you change the public response. People don’t just ask “what is CDR?”; they ask “who’s in charge?”

🔍 Before We Scale, We Need Trust: Early impressions matter. And in a landscape primed for misinformation and polarisation, how we communicate now will shape the governance, justice, and legitimacy of CDR for decades to come.

In the second of our three-part deep dive, we plunge into the murky, acronym-rich depths of carbon removal policy across the UN, the EU, the US and beyond - and we promise to come up for air, eventually.

In this episode:

🧠 Acronyms and Initialisms Aplenty: Consider yourselves warned. This episode contains more letters than a game of Scrabble. Don't worry, it'll be quacking... sorry, cracking.

🌐 The UN – Going Global: We finally (finally!) get to grips with Article 6 of the Paris Agreement - the big hope for creating a global, compliance-grade carbon market. So, does it deserve its place as the darling of the CDR community?

🧱 The EU – Slow and Steady Wins The Race: We dissect Europe’s tripartite climate framework, learn what the CRCF stands for, and ponder the possibility of removals entering the ETS by 2031 (yes, we said 2031… pace yourselves.)

💵 The US – Land of the Free… Tax Credits: While the EU leans into regulation, the US has chosen financial incentives to scale engineered CDR… for now. (Content advisory: information likely to be outdated within minutes.)

🌏 Zooming Out: Switzerland is quietly blazing a trail. Japan is scaling up a national carbon market. India is laying the foundations. There’s a lot going on out there, if you’re willing to look.

🧩 Policy vs Reality: We explore how the right policy for the right place might be the secret to scaling CDR globally - and why no single blueprint might work for everyone.

Welcome to the first in a Carbon Removal Show three-part policy miniseries! We’re diving into the bureaucratic spaghetti of CDR policy - what it is, why we need it, and why pretending it doesn’t exist is no longer an option. It’ll be fun – we promise.

In this episode:

📜 Policy 101: What do we mean when we talk about carbon removal policy? Tom, Emily and their guests unpack the layers - from global frameworks to national targets, and the many policies themselves that can (hopefully) keep this show on the road.

🏛️ A Brief History of Climate Governance: We rewind all the way to the UNFCCC, the Kyoto Protocol, and the Paris Agreement, to understand the context in which CDR policy is emerging. Turns out, carbon removal has technically been part of the discussion for some time - but it took a while to step out of the LULUCF shadows and into the limelight.

🛠️ The Goals of CDR Policy: Whether it’s support for scaling the industry or regulation for doing it right, we explore the many roles that policy can play in ensuring CDR does what it’s supposed to. Who should pay for it? How can we avoid unintended consequences? And is it too late to bribe policymakers with Emily’s banana bread?

🌍 It’s All Connected: We learn that CDR doesn’t happen in a vacuum – and that means CDR policy can’t either. It's entangled with everything from energy to land use to ocean governance. And yes, ocean-based CDR is complicated when 40% of the sea has no nation.

🍖 The Bony Meat Pie Metaphor™: How do NDCs, interim targets and policies work together to meet(/meat?) our climate goals? It’s all very clever, but not especially appetising.

🧪 Avoiding Déjà Vu: We ask what we can learn from previous climate and environmental policies – so we don’t spend the next decade reinventing the wheel, crashing it into a forest, and accidentally calling it carbon neutral.

Welcome back to The Carbon Removal Show! We’re kicking off Season 4 with a view from the top - checking in on the state of the carbon removal industry here in the dizzying heights of 2025.

In this episode:

🌍 Where are we now? Durable CDR purchases hit 8 million tonnes in 2024 (a 78% bump from 2023), but 64% of that was Microsoft flexing. Deliveries? Still catching up – and most of it’s biochar.

📉 Caveats, ahoy: Sales are booming, but actual removals are still lagging. The buyer pool is basically a tech giant party.

🚨 Bubble watch: Are we living in a beautifully optimistic carbon bubble? Is it about to pop? Will Tom’s optimism hat survive the bubble bath? We explore industry hype vs. hard truths, including the risks of undelivered credits and startup casualties.

📊 The vibe check: Emily’s on an emotional rollercoaster. Tom is backing the CDR horse. Ben’s beard is greyer. Collectively, we’re cautiously hopeful.

🛠️ What needs to happen?: Scaling isn’t just tech - it’s finance, policy, public understanding, and clear comms. We need to get the message out of the bubble and into the next layer of the onion. (Just… not into Emily’s bubble bath. Please.)

🚗 A history lesson you didn’t know you needed: Did you know the best-selling car in 1897 was electric? We could’ve been 100 years ahead… but markets are messy.

What happens when an individual company bakes industry scale up into their business philosophy? In this episode, Jakob Andersen shares the “gigaton thinking” mindset that drives his company, MASH Makes, in their approach to business and biochar.

MASH Makes started as a project at the Technological University of Denmark focusing on technology that could convert various waste streams (mainly residue biomass) into different energy products. In short, MASH Makes use automated machines that are able to produce bio oil, hydrogen and electricity from agricultural waste, with the main byproduct of this process being biochar – a soil amendment that actively absorbs CO2 from the atmosphere.

Big thanks to MASH Makes for supporting this episode.

With scaling up in mind, this episode dives into an innovative concept that could help the industry take big steps forward. Tom and Emily are joined by Jonny Gilson from Carbonaires and Professor Niall Mac Dowell from Imperial College London to discuss Carbonaires’ ideas for the future of the voluntary carbon market.
